Given numbers are 630, 385, 291, 257

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 385 are 5 x 7 x 11

Prime factors of 291 are 3 x 97

Prime factors of 257 are 257

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 630, 385, 291, 257

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(630, 385) = 6930

GCD(630, 385) = ( 630 x 385 ) / 6930

= 630 / 385

= 630

Step2:

LCM(35, 291) = 10185

GCD(35, 291) = ( 35 x 291 ) / 10185

= 35 / 291

= 35

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 630, 385, 291, 257 is 1
